            When you are making more than one request with <code class="code">Zend_Service_Delicious</code> to speed your
            requests, it's better to configure your HTTP client to keep connections alive.

                When a <code class="code">Zend_Service_Delicious</code> object is constructed, the SSL transport

                <code class="code">'ssl2'</code>. This is because del.icio.us has some problems with <code class="code">'ssl2'</code>, such
                as requests taking a long time to complete (around 2 seconds).
